How do I find my silicone ring size?

Finding your perfect ring fit will not only make wearing your ring extremely comfortable and more breathable, but will also boost the longevity of your ring.

Let’s get started!

Finding Your Perfect Fit:

Method 1: Use the ring sizer included
If you own a Knot Theory ring or knows someone who does, a free paper ring sizer is included with your ring. If it's a red ring sizer (our latest), fit it around your finger normally and measure. If it's a gold ring sizer, make it more snug on your finger before reading the measurement.

If you are a half size, we recommend going half size down. e.g. If you are a Size 10.5, we recommend the Size 10 ring.

Method 2: Print out our free ring sizer
This is another accurate way to find your perfect fit. Ensure that the guide is printed at 100% scale, so the sizing is as accurate as can be.

Method 4: Visit a Jeweler
Jewelry stores are another good way to get your size measured.

What if I’m between sizes?
Our silicone rings come in whole ring sizes only, because the flexible silicone rings are more “forgiving” and half sizes are not needed.

If you are in-between sizes (e.g. size 10.5), for comfort fit rings, we recommend sizing down (size 10), for other rings, we recommending sizing up (size 11). 

Are comfort fit rings sized differently?
We are very excited to be the only brand to offer comfort fit silicone rings! Comfort fit rings offer more comfort and breathability, because of the curves inner surface. Whether it’s a metal or silicone comfort fit ring, size down by 1 size. If you are a size 10, choose size 9 rings. If you are a size 10.5, choose size 9 or 10.
